.TERBIEN E-LQBENCE McKENNA, or LINIDON, coLonAro.

To all who/11bit may concern; Be it known that l, TeRmENcE'LonnNon MCKEN NA, citizen 1055 the United :States, iresiding at Lindon,in-zthe county .of Washington andtState' of @olorado, have invented certain"; new and useful Improvements in Resilient 'Wheels, of which the following a specification, reiienence zbeingwhad .to the accompanying,drawings: s ,It' This nvention relates. to an improved resilient .wheel, particularly adapted for use in connection with automobiles. :As one of the iobjects of the invention, itv isJ-the :aim :to provide simple, efficient and practical means; of connection between the hub and-the rim ofthe Wheel.

The invention further aims to provide resilient means for the spokes, mounted upon the hub, .and-also-to provifde means for connecti-ng the resilient means tothe hub. V

The "invention further .aimsito provide means to prevent creeping-of the resilient means'with relation tothe hub.

The invention further'aims to provide improved connections between the spokes lot the wheel .andthe rim, said connections .being oi such character as to permit :thespokes to cooperate with the resilient means; to Ein-' 1 sure resiliency forithe wheel.-

While the .designand construction at present illustrated and set {forth is deemed preferable, i-t 'is :ob-vious'that as a result of a reduction of the invention to amore practical form tor coimnercial purposes, theinvention may-be susceptible ofchanges, and the right to these is claimed, provided they are comprehended within the scope of what is claimed. I

The invention comprises further features and combination of parts aswill be hereinafter set" forth, shown in the drawings and claimed. 3

In the drawings:

Figure 1 is a view inside elevation and partly in section of the improved resilient Wheel constructed in accordance with the invention.

Fig. 2 is a sectional view on line 22 of Fig. 1, more clearly showing the mounting of the resilient means of the hub, and illus-' trating the hub as being constructed in two sections.

resilient means, and the. connection between thetresilient meansand the hub.

' -IRefeI-ring more especially to the drawings 1 and 2 designate-the two sections of the hub, which are interconnected vas shown at 3, there .being bolts a penetrating the two sec tions for. fastening them together.

The two sections of the hub are provided 7 with annular recesses :5 angular in crosssection, which, when the two sectlons are connected, form a channel. The bottom of the channel constitutes a seat'for a pluralityof coil springs 16', there being a circular rod orbolt' i passingthrough the coils to anchor them in the channel. The adjacent ends of the rod-or bolt are connected by a suitable turn buckle-8. Bymeansof the "buckle .or rod the; bolt may ibe 'securely' tightened,

wherebytthe springs inayfbe fastened place firmly. i

The flanges 9 and 10 of the hub sections are provided with radial slots 11 and 12. It is :to be noted that the slots 11 of one of the fiangeswa re in staggered relations with the slots 12 of the opposite flange. The end portions .of each coil spring are/extended laterally, constituting arms 13, the outer end parts of which are turned to 'form coils 14L.

The extremities '15 beyond the coils-14 are fastened in any suitable manner into the inner ends of the spokes 16 of the Wheel. These spokes may be constructed of any suitable material preferably wood, and their inner partshave surrounding steel sleeves 17 to reinforce the :spokes, and-to prevent them from splitting, incident to the strain'of the arms in the spokes. I It is to 'benoted that the notches the flanges are arranged in staggered-relations, for the accommodation of the spring arms which project laterally fromthe coil springs, 'wliich'ai'e-mounted'in "the channel of the hub. In other creeping of the coil springs relative to the circular bolt or rod. Obviously this is accomplished owing to the arms contacting with the walls of the notches. The adjacent faces of the flanges of the hub are provided With annular shoulders 18, to be engaged by a retaining band 19. This band overlies the coil springs and prevents radial displacement of the springs.

Carried by the inner" face of the rim are spring steel plates 23, .Which are secured to the mm as shown at 24:. Theseplates are V-shaped, and have openings 25, through which the spokes movably-pass. The ends of the spokes areprovided with'reduced porti0ns:26 and adjoining shoulders 27 The inner "face of the rim has secured thereto flanged members 27, into which the coil springs 28 extendand engage. These coil springs in turn receive the reduced portions of the outer ends of the'spokes, said springs contactin with the shoulders, thereby insur-' ing additionaliresiliency-forthe Wheel. I

y The invention having beenset forth, what is claimed as newand useful is: i i

21 In a lresllient wheel, the combination with a hub member provided with. a channel,

of a plurality of coil springs secured in the channel concentricallywith the hub, said springs having laterally exte'ndingspring arms, a rim,'and spokes connecting the rim and the spring arms, and means carried by the hub member receiving and cooperating .withthe spring arms to prevent'creeping of thecoil springs in the channel.
